This tag should not be used for:
- small valleys with known permanent or regularly occurring waterflow - use waterway=stream instead. natural=gully is primarily for cases with no regular or unknown water flow.
- larger valleys or stable relief forms with no fresh signs of erosion - use natural=valley instead.
- man-made ditches - use barrier=ditch
- steep relief edges due to larger scale erosion - use natural=cliff or natural=earth_bank instead.
